, The neutralizenineans lincludes pneu! *tralizer' rods e, neutralizer gates "ffandneu tralizer levers g, and the selector means@- t.

includes a selector ram h, selector heads' j carried by the ram 71, and selector rods m and a, and selector indicator means o. The control means D includes a shaft p and means g Jor'turning said shaft, and a trigger member 7". l A A The neutralizer means in combination with the selector means and the Control means cooperate to eiiect one or more levers lil of which in the showing there are two, as s and t.

rl"he levers s and t are the levers to be ac-V tuated,` as stated, and said lever-scare in turn adapted to control movement of gears such those shown tor instance in Figure at u. rlhe said levers s and t may be actuated at the same time in any number ci directions, or one oi said levers may be held in what may be termed a neutral position; that is to say, a position such as shown in Figure 1 in Ylull lines when the other lever is moved.

An end plate i2r is formed with'an opening 3 and adapted to be passed through said opening is bearing mem er 4 constituting a part of the means g. The end plate may be held to the casing by suitable means such as screws 5 and thereby close'an end of they compartment I). The bearing member 4 is formed with screw threads'at G, andthe means g further includes Va lever 7 which is carried upon the member 4 and held to said member by a nut 7 screw-threaded upony the threads 6. The bearing member 4` is formed with a key 8 received in an axial` spline 9 on the shaft p. It is thus evident. that rock.- ing the lever 7 will in turn rotate the Shaft y). Carried on the shaft p is a stepped Cols lar 10 the. first` step of which is provided with a key 11 andthe second step oit which is provided with a transverse tapered bore adaptedto align with a bore in the shaft, y) whereby a pin 12. may be lpassed through said bores for locking the stepped vcollar 1 0 Vto the shaft p. rIhe ram his annular in for,-

mation and formed with steppedl bores 13 and 14, the bore 13 being'ofia diametervrcorresponding to the diameter of; one Ot the collars 10, andthere is likewise a longitudinal groove 15 opening within, the bore 13 and within which groove ythe key` 11 is received. rlhe second bore14 is aproximately oit a diameter equal to the diameter of the shaft 7). The head portion 160i' the ram 7L is provided with a bore 17 concentric with the bore 14 butot greater diameter, and rsaid bore is adapted to receive a tlai'ige 13 car# ried by the shaft p. From the descriptionV as given so tar it will be evident that rotation ot the shaft p will likewise rotate the ram h, due to thelt'act that the key 11 by fitting within the key-way or groove -15fwill give a locking relation between the Shaft and the ram. Adaptedto surround the Shaft p and within the bore 13 is a spring 19which abuts against the flange included between of the sides.

the bores 13 and 14 and a tace of the collar 10. yThe ram is provided with a peripheral groove 2O which serves to divide the ram intoV two zones, one oiwhich as 21 carries the selector heads j, while the second portion Q2 isy formed with a series of spaced flutes 23. The ram is likewise formed vwith -a series of longitudinal bores o in the part 21 ot said ram, and which bores may be termed selector bores.

The partition d is provided with a bore Q4 adapted to receive the shaft p and said partition is further provided with two bores as shown at and 26 within which are received the selector rods 'm and fn. The bores Q4, Q5. and 26 extend between the chambers or compartments Z2 and Ac. The partition is further provided with two stepped bores which` extend transversely between the chambers Z2 and o as shown at 27 and 28.' One of the bores of each stepped portion 2T and 28 is ot, greater, diameter than the other bore, and each rod c carries a collar Q9, there being contractile members 3 0 within the bore and surrounding its respective rodi@ and interposed between the flange separating the large and smallbore and the collar 29, whereby the rods e are at all times normally actuated in one direction. A plate member 31 is adapted to be attached to a tace of the partition d, as by means of screws 32, and saidplate is providedwith bores 33 and 34 through which reduced ends 35, 36, 37 and 33 off the selector rods m and n may be passed. 'Ehe plate is likewise provided with two bores 39 and 40 for the neutralizer rods e. It will be understood that these bores in the plate are formed so as to be in alignment with the respective bores in the partition d; However, the'boresv in the plate 31 for the selectorv rods accommodate only the reduced ends ot said rods so as to restrict movement o'l the selector rods in one direction when the shoulders 41 between the, reduced ends andthe main'body oi the rods contact with the plate. 'lt is obvious that the plate 31 would stop movement ot the. neutralizcr rods when the collars Qi) contact with said plate.

ithin the chamber c are the gates f and levers g, as well as the main levers s and t. Side walls 42 and 43 forming in part said Vchamber c are provided with journal mem bers 44, 45, 46 and 47. The journal portions 44.and 46 arein alignment, as are the journal portions and 47, and shafts 48 and 49 are carried in the journal portions The shaft 43 carries the levers g of which two are provided, as shown at 50 and 51, each lever having a hub portion 52, said-hub portions abutting, and likewise abutting with the hub portion of the journal portions of the sidessol as to hold' them in close working relation and l tion ofeachzleverf The shaft49 looselyvearo, rie'sjitliereon "the" leversl 9 'and y t, as' shov'vnv 'at' [11j -aud-54E, 'andea'eh leverfi's provided With:

dication that a second position is. assumed by said ram. It we call this position 1, as shown in Figure 12, the neutralizerrod openings o, of which there are a number corresponding tothe number ci. selector heads j, are brought into such a position that one of the neutralizer rods may enter within one of said openings. ln the,f position ot the ram shown in Figure llthe` upper neutralizerrrod c may enter the neutralizer opening o as shown at 86, and one oi the selector rods m, namely, the one shown at 35, will be in alignment with one of the selector heads shown at 87. The other selector rodsrare out oi' alignment with the heads j. The lower neutralizer rod e indicated by the dotted line in Figure V12 at 88, will contact with the ram 7L when the ram is moved. It we push the shaft y? inwardly in the direction ot the arrow at the right-hand end of Figure 1, the beveled or cone-shaped nose 77 of saidshai't p will Contact with the plunger or pin .70 and liit the same. However, it is evident lthat the shaft will have to move a considerable distance inwardly betere the plunger is lifted high enough to cause the notch 6%) carried by the lever 66. to be. entirely lifted `from the peripheral groove 2O ot the ram so that the notch or projection 69: may escape over the wall S9 of the rain. By the ram not moving-and the shaft moving inwardly, the spring 19 will be compressed,

and when the plunger 70 has been raised al suiiicient distance towli'ft the projection' 6.9 from Contact with the wall 89, the spring will expand suddenly .and force the ram first against the lower neutralizer rod c moving it inwardly their followed bv movement of the selector rod m show-n at 35, when the selector head shown at 87 contacts therewith. The other selector rods will slide over the periphery of the ram without contacting with any ot thezheads j, as has been stated, and the lower neutralizer rod c will enter the opening-o at 86. This resultant movement of. .the-parts is shown in VFigures 3 and 4, in which it will lie-seen that the end ot thelower neutralizer rod e has contacted with the nose 62 ot the lever g shownat 51, and rotated said lever in such a manner that they opposite'end oi the same has contacted 'with the gate f shown at 57 and forced the sameagainst the lever "t. This movementA willi cause the lever t to assume an' upright position like that shown in the full lines of Figure-1 for the lever s, inasmuchas bothingers (3f-gt and 65 of the gate contact with the-v lever t on opposite sides oi: the'pivotpoint' of said lever. The heady' shown at S7, as stated, contacts with the selector rod m-shown at 35 and forces the same inwardly, and this inward movement of the selectorf'rod causes the end ot the same to Contact with the levers shown at 53, and.Y causes the saine to pivot about its shaft 49 and into the position shown-iii Figure l in which it is seen that 'the upper endv as 90 is moved anti-clockwise aboutthe shaftV 4:9. From the stateinentof the operation,V as just given it is evident'that one lever t is maintained in an upright posi-tion or what is` termed a neutral position, when the other` lever is to be moved to a given position, and further, attention is directed to the tact that the neutralizer rods c are of a length sutlicient to cause them to contact when inthe p'ositioil shown in Figures 1 and 2, with theneutralizer levers `g, while the selector rods mano' n are out of contact with the levers s and t. In other words, there is a differential movement in which one of the levers gi, depending uponv which one is to be moved iirst, throws one of the levers, for-'instance t, into a given position before a selector rod contacts with the lever s to be moved; that is, one of the levers s or t always moves to neutral position before'the other lever assumes a position other than neutral. It the shaft p isinow pulled outwardly in the direction of the arrow at the right-hand side of Figure 3, the lever 66 will slide over the periphery ofthe part 22 of the rain h until the projection 69 enters the notch or groove 2O and holds the ram vin retracted position. The neutralizer rods under action ot the spring 30Y will move inwardly so that they again assume the position. shown in Figure 1. However, the selector rod m shown at 35 will remain in the position shownv in Figure 3, as will likewise the gates f and the lever s which has-been moved` This will bte-particularly true Jfor the levers providing it has `moved a for-lz member 91, as

shown-inv Figure 5, to a given position, whereby a gear 92 is caused to mesh with a second gear. It we rotate-'the shaft y) through the medium ot the handle 7 back to the position termed neutral in which the ram would appear as shown in Figiue 13, then push theshait 29 inwardly so that tinI same compresses the spring 19, due to the tact tha-t'the ram cannot move until the trigger releases the same, the ram will `upon suchrelease move forward under impetus given the same by the stored up energy in the compressed spring, andit will be seen upon reference. to Figure 13 that the up per andi lower neutralizar rods e will contact withfthe end- 16 of said ram, sai'dneutralizer rods not entering.v any of the openings or bores e, withtheconsequence that said rods are moved inwardly` forcing the levers 'g tof pivot .about the shaft 48 with theopposite ends of said levers contacting withthe gates-'f swinging said gatesinwardly so vthat the fingers of the same contact with-the levers s and t andthereby moving said levers into an upright or what has been shown in'FigureseS and A10,jand-itwill. be
